Svid39/marine_checklist_app ? reverse-engineered prompt

Build me a Flutter mobile app for vessel inspections that helps seafarers and inspectors run PSC, ISM, Class, and similar checks from a phone.

I want the app to let users create and manage checklists, fill them out offline, mark non conformity items, add notes, and attach photo evidence to each item. It should save everything locally so it works even with no internet, and it should feel polished and easy to use on a ship. After an inspection, the app should generate a professional PDF report from the checklist results, include the photos and findings, and let the user share or email the report right from the device. Please make the main screen useful for browsing saved inspections and keep the whole experience simple and dependable. If you need to, look up current Flutter and PDF generation docs online before implementing the tricky parts.
